These are quality no-show socks that are working out well for me. The material is medium thickness, in other words they are thicker than the thin "shoe liner" type socklets that are made mainly to wear with dress shoes, but they are not as thick as the padded cotton kind made with runners or athletes in mind. There are a good in-between thickness that makes them versatile so you can wear them with lots of different shoe styles. I am mainly wearing them with sneakers and am pleased with them for this use.There are soft silicone gel heel grippers that keep the socks from slipping down. I also like that the toe seam does not cause any irritation or pain even after wearing these all day with snuggly tied shoes. The fabric is stretchy for a good fit. I chose the size 5-7 option and they are definitely sized for women. On a trip out of town, my husband realized he had forgetten his no-show socks, so I gave him a pair of these, but they wouldn't stretch over his men's size 12 feet. They fit my women's size 7 feet perfectly, so keep size in mind and order accordingly. Most socks come in one size to fit a wide range of feet, but these are sized much more specifically.Overall these are great medium weight socks that do not show with most shoes, are mostly cotton for comfort and absorbency, are have soft heel grippers that keep them from sliping down. They are high quality and I am pleased with them.
